' 6 claims... (01. 154-.-29)

My present invention relates to machines for making batting as a continuous process from cotton, jute, animal hair and many of the other familiar fibrous materials commonly used in structures of this kind and the. invention has for its, object to provide a simple, eflicient, and durable machine of this character embodying certain advantages and improvements relating generally to the feeding of the stock in a manner that insures a thickness at the edges equaling that at the center; to the means for conveying the bat after it leaves the forming mechanism, and to provisions in connection with the latter wherebysewing, to obtain a quilting eifect, is facilitated.

, 'To these and other ends the invention resides in certain improvements and combinations of parts, all as will be hereinafter morefully described, the novel features In the drawings;

Similar reference numerals throughout the several views indicate the same parts.

An understanding of the operation and objects 'of my machine can best be understood after an understanding is had of the article which it is its object to produce.

Referring to Figs. 9 and 10, ,I there show 'a tenaciously t0 the bat and particularly to the being pointed out in the claims at the end of the specification.

vided with openings 6 into which the raw stock suction pipe 8 connected with a blower .9 to a for lint. The apron l2 delivers to a Garnett elerolls l9 and then sewed to the .through; pressure rolls 21, the liners or outer 'ciated mechanism, shown particularly in Figs. 7

strip of batting such as is used to insulate the walls of buildings and the floors and ceilings, although the making of carpet linings and similar objects is within the scope of the capabilities of a the machine. This particular product consists of an interior felt-like center or core iconsistihg of the materials hereinbefore named having sewed to it at lateral intervals a number of paper strips 2. The strips are in pairs on opposite sides oi the bat in alinement so that they assist in holding the body of the bat in shape. on each side of the structure so far described, there is applied with an adhesive, such as glue or silicate of soda, paper liner strips 3 and 4 which adhere 7O sewed paper strips 2. My machine assembles and combines all of these elements as a continuous process.

Referring now more particularly to Figs. 1 and 2, I will describe briefly the whole machine and the course of the stock therethrough to the point of delivery and later describe more in detail the particular elements in which my invention resides. A hopper, indicated generally at 5, is profrom the bales is shovelled through doors or openings 6. It contains feeding or picking mechanism that preliminarily disintegrates the lumpy mass. It is then drawn froma chest '7 by meansof a feeding chamber 10. A conveying and picking apron 10a carries it from the bottom of this chamber and dumps it into a chute 11 from which it falls in finely divided form by gravity upon a horizontal feeding apron 12. 13 is an exhauster ment 13a which in turn delivers to forming rolls l4. Issuing from the forming rolls the bat passes between driven rolls 15 that guide it-over a short table 16 upon an apron 17 running over rolls 18 endlessly; The strips 2 are applied from supply bat immediately a sewing mechanism 20. .Pfassing thence paper sheets 3 and 4 are applied to the upper and lower sidesas drawn from supply rolls 22 and 23 and after trimming at 24, the finished bat is drawn up an. incline 24a. 25 and 26 are the pasting or adhesive applyingunits for the liners. At the end of the incline, as shown in Fig. 2, is

a swatch-lug mechanism indicated generally at 27,

which delivers it in bales 28 but which'need not be further described.

, Now describing in detail the chute 11 and asso- 1 and 8, it will be seen that the mouth or delivery end of the chute is over the apron 12 above mentioned, which apron runs over rollers 29 journaled in a trough-like member having upwardly extending side flanges 30. The belt 12 fills substantially the entire width of the trough-like member betweenthe flanges 30, and these flanges 30 define the width of the bat which is formed on the apron l2 and delivered thereby to the Garnett picker 13a.

It has been found in actual practice that when the chute 11 which delivers the stock to the apron 12 is throughout its length of only the same width as the bat which it is desired to form, there is a tendency to deliver more stock to the center of the bat than to the edges thereof, which tendency seems to be due to a retarding effect caused by the side walls of the chute upon the stock passing therethrough. Consequently, the stock delivered to the apron is noticeably thinner at the edges than at the center, with the result that an improper bat is formed when it is desired to make a bat of uniform thickness throughout its width.

It has also been found in actual practice that this tendency to form a bat thin at the edges is overcome if the chute throughout the major portion of its length be made somewhat wider than the width of the bat to be formed, the chute being tapered or contracted at its delivery end to the width of the bat desired. Such a construction is shown clearly in Fig.8, where it will be seen that the side walls of the chute are tapered or inclined inwardly and downwardly at 32 to the bottom edge 31, which forms the delivery mouth, this delivery mouth being substantially equal in width to the space between the upstanding flanges 30 which is the width desired for the bat. Above the tapered portions 32, however, the side walls of the chute may be substantially straight and parallel with each other, as shown, and here the chute is materially wider than the width of the bat to be formed. The lines 33 projected upwardly from the delivery mouth show the width of the mouth in comparison to the width of the main portion of the chute above the mouth. The conveyor 10a delivers stock to the upper end of the chute substantially throughout the entire width-thereof. It is found in practice that with this construction the bat material delivered to the apron 12 is of substantially uniform thickness throughout the entire width of the bat, the edges of the bat as indicated at B being as thick as the center of the bat. Thus there is produced a bat having the desired characteristics of uniform thickness, notwithstanding the retarding effect of the side walls of the chute on the stock passing therethrough.

Referring now to Figs. 1 and 3, it has heretofore been the usual practice to provide a table of substantial length beyond the forming rolls 14, over which table the bat is thrust by the driving rolls 15. It is found in practice, however, thatat this stage of its manufacture the bat is frequently not sufficiently strong to be thrust over a table of any substantial length, and likewise it is not strong enough to be pulled over the table by pull rolls. Hence, according to the present invention, there is provided a conveyor apron at this point which receives the bat almost immediately after it issues from the feed rolls 15 and which conveys it forwardly without pushing or pulling strain. I

Preferably this conveyor apron comprises a plurality of laterally spaced belts 36, as best shown in Figs. 5 and 6. The spaces between the 2 have been sewn to it and the bat is then sufficiently strong to continue its further travel without the aid of this apron.

Means is preferably provided for sprinkling a chemical (for example, a granular salt) upon the bat for the purpose of making it fireproof or verminproof. This means may comprise a hopper 39, shown especially in Fig. 3, having at its mouth a sprinkler or agitator 40 arranged to deliver the chemical onto the bat at a point subsequent to the attachment of the bottom liner 4 and prior to the attachment of the upper liner 3. Since the chemical is sprinkled upon the top of the bat, it is desirable to provide means for causing it to permeate thoroughly the texture of the bat material, and there is accordingly provided an agitator 41 (Figs. 3 and 5) driven by a chain 42 from an independent motor 43. This agitator 41 is preferably in the form of a rotary member having one or more fins (two being shown in the drawings) which, upon rotation of the member, contact with the under surfaceof the bat, the impact causing a slight shaking of the bat which shakes the chemical into the bat material and causes it to permeate such material thoroughly.

While one embodiment of the invention has been disclosed, it is to be understood that the inventive idea may be carried out in a'number of ways. This application is therefore not to be limited to the precise details shown, but is intended to cover all variations and modifications thereof falling within the spirit of the invention or the scope of the appended claims.

I claim as my invention:

I v
